11. Mechanisms and genes controlling the signalling network for biotic and abiotic stress defences in Arabidopsis thaliana (L.) Heyhn : Functional cross-talk between photo-produced reactive oxygen species, photosynthesis and plant disease defence responses
Abstract : Excess excitation energy, mechanical injury and defence against pathogens, each trigger rapid production of reactive oxygen species (ROS) in Arabidopsis thaliana leaves. ROS, such as hydrogen peroxide (H2O2), are required for the induction of systemic acquired acclimation and may lead to redox changes in photosynthetic electron transport (PET). READ MORE

12. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco
Abstract : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. READ MORE

13. Altered gene expression in the human airways during oxidative stress
Abstract : The atmospheric accumulation of pollutant gases, such as N02 and ozone, has been associated with an increased airways hyper-reactivity within the healthy population. Moreover, those with conditions such as asthma and chronic obstructive pulmonary diseases generally experience an exacerbation of their symptoms upon exposure to these noxious gases. READ MORE

14. The oxidative and osmotic stress responses of S. cerevisiae
Abstract : The yeast Hog1 is a stress responsive mitogen activated protein kinase (MAPK) similar to mammalian p38 and JNK. Rck2 is a protein kinase downstream of Hog1. The Hog1 pathway was previously implicated exclusively in the response to osmotic stress. READ MORE

15. Influence of oxidative stress on aryl hydrocarbon receptor signaling
Abstract : The aryl hydrocarbon receptor (AHR), a multifunctional protein and a key regulator of drug metabolizing enzymes, belongs to the basic-helix-loop-helix (bHLH)/PAS (Per-Arnt-Sim) super-family of transcription factors. The AHR responds to exogenous and endogenous chemicals by induction or repression of a large number of genes involved in many physiological processes and normal development. READ MORE
